Abstract

DISPOSITIVO SUPRESOR DEL ECO. DISPOSITIVO SUPRESOR DEL ECO (DSE) QUE RECIBEN LOS ABONADOS DE UN SISTEMA DE COMUNICACIONES, QUE SE CONECTA EN LA PARTE DEL ENLACE A CUATRO HILOS Y QUE COMPRENDE DOS ATENUADORES DE SEÑAL (AS1 Y AS2) QUE APLICAN LA ATENUACION QUE DETERMINA UN CIRCUITO DE CONTROL DE ATENUACION (CC), DOS DETECTORES DE VOZ (DV1 Y DV2) QUE GENERAN UNAS SEÑALES DE VOZ (SV1 Y SV2) CON LAS CUALES EL CIRCUITO DE CONTROL DE ATENUACION (CC) DEFINE LOS ESTADOS DE LA COMUNICACION POR LOS QUE PASA LA CONVERSACION ENTRE ABONADOS; SIENDO LA ATENUACION APLICADA FUNCION DE LAS SEÑALES DE VOZ (SV1 Y SV2), DEL ESTADO ACTUAL Y DEL ESTADO ANTERIOR AL ACTUAL DE LA COMUNICACION. EL CIRCUITO DE CONTROL DE ATENUACION (CC) RECIBE Y GUARDA EN CADA INSTANTE LOS CAMBIOS DE NIVEL DE LAS SEÑALES DE VOZ (SV1 Y SV2) PROCEDENTES DE CADA UNO DE LOS DETECTORES DE VOZ (DV1, DV2).ECO SUPPRESSOR DEVICE. ECO SUPPRESSOR DEVICE (DSE) RECEIVED BY THE SUBSCRIBERS OF A COMMUNICATION SYSTEM, WHICH IS CONNECTED AS PART OF THE FOUR-WIRE LINK AND INCLUDES TWO SIGNAL ATTENUATORS (AS1 AND AS2) THAT APPLY THE ATTENUATION THAT DETERMINES A CIRCUIT CONTROL OF ATTENUATION (CC), TWO VOICE DETECTORS (DV1 AND DV2) THAT GENERATE SOME VOICE SIGNALS (SV1 AND SV2) WITH WHICH THE ATTENUATION CONTROL CIRCUIT (CC) DEFINES THE COMMUNICATION STATES THROUGH WHICH THE CONVERSATION PASSES AMONG SUBSCRIBERS; BEING THE ATTENUATION APPLIED FUNCTION OF THE VOICE SIGNALS (SV1 AND SV2), THE CURRENT STATUS AND THE PREVIOUS STATE OF THE COMMUNICATION. THE ATTENUATION CONTROL CIRCUIT (DC) RECEIVES AND SAVES IN EVERY TIME THE CHANGES IN THE LEVEL OF THE VOICE SIGNALS (SV1 AND SV2) FROM EACH OF THE VOICE DETECTORS (DV1, DV2).
